McDonald's can afford to pay its workers a living wage without sacrificing any of its low menu prices, according to a new study provided to The Huffington Post by a University of Kansas researcher.

Doubling the salaries and benefits of all McDonald's employees — from workers earning the federal minimum wage of $7.25 per hour to CEO Donald Thompson, whose 2012 compensation totaled $8.75 million — would cause the price of a Big Mac to increase just 68 cents, from $3.99 to $4.67, University of Kansas research assistant Arnobio Morelix told HuffPost. In addition, every item on the Dollar Menu would go up by 17 cents.

Morelix looked at McDonald's 2012 annual report and discovered that only 17.1 percent of the fast-food giant's revenue goes toward salaries and benefits. In other words, for every dollar McDonald's earns, a little more than 17 cents goes toward the income and benefits of its more than 500,000 U.S. employees.

Thus, if McDonald's executives wanted to double the salaries of all of its employees and keep profits and other expenses the same, it would need to increase prices by just 17 cents per dollar, according to Morelix.
